Great Dark Spot

Researchers found that Titan's ice shell, which overlies a very salty ocean, varies in thickness around the moon, suggesting the crust is in the process of becoming rigid.

In this movie from NASA's Cassini spacecraft, the gravitational pull of Saturn's moon Prometheus creates patterns in Saturn's F ring. This movie also happens to show a small trail of icy ring parti...

Each of these two montages shows four synthetic views of Titan created using data acquired by the visual and infrared mapping spectrometer (VIMS) on board NASA's Cassini spacecraft between 2004 and...

On May 12, 2007, Cassini completed its 31st flyby of Saturn's moon Titan, which the team calls T30. The radar instrument obtained this image showing the coastline and numerous island groups of a p...

Saturn's moon Pan, orbiting in the Encke Gap, casts a slender shadow onto the A ring. For a closeup view of the "flying saucer" shape of Pan (28 kilometers, or 17 miles across), see Saturn's Sauce...

Saturn's F ring, which appears kinked and gored in many images, looks straight here. Above the brighter core, the ghostly strands of the F ring's outer envelope, which has a spiral arm structure, a...

The bright arc within Saturn's G ring is shown truncated by the shadow of the planet at the bottom of this image.

This is an artist concept and movie of the view from Cassini during the star occultation that detected "Mittens," the small object to the right of the star. As Cassini watched the star pass behind ...

The Huygens probe descends through Titan's murky, brownish-orange atmosphere of nitrogen and carbon-based molecules, beaming its findings to the distant Cassini orbiter. The probe is equipped with...

Cassini bids farewell to Saturn’s yin-and-yang moon, Iapetus. This image is from the last set of observations Cassini made of this world of striking contrasts. 

The most visually striking feature on Saturn’s icy moon Tethys is Odysseus crater.

Saturn's dynamic F ring contains many different types of features to keep scientists perplexed.

NASA's Dawn spacecraft views a crater at top center that touches the rim of Messor Crater (25 miles, 40 kilometers), shown at left.

Seasonal changes in the atmosphere of Saturn's largest moon are captured in this natural color image, which shows Titan with a slightly darker top half and a slightly lighter bottom half. Titan's ...

As seasons change on Saturn, and sunlight creeps farther north, the region surrounding the north pole is steadily coming to light. This scene reveals many features in Saturn's dynamic and beautifu...

Cassini peeks at Saturn's relatively dark south pole, providing an up-close look at the haze-free upper atmosphere there. The banded structure around the pole seems to be superimposed on the chara...

This is the first global map of the giant asteroid Vesta composed from images recorded by the framing camera aboard NASA's Dawn spacecraft. The equator is running parallel to the upper image border...

NASA's Cassini spacecraft took this raw image of Saturn's moon Titan on Oct. 14, 2010, kicking off an action-packed long weekend that took the spacecraft by eight other moons. The camera was pointi...

From hundreds of thousands of kilometers away, the Cassini spacecraft spies craters on the surface of the moon Janus. This view looks toward the Saturn-facing side of Janus (179 kilometers, or 111...

Mercury: Computer Photomosaic of the Southern Hemisphere

Enceladus looks as though it is half lit by sunlight in this view from NASA's Cassini spacecraft, but looks can be deceiving.

Cool and icy Dione floats in front of giant Saturn bedecked in a dazzling array of colors. The surface of Dione, which exhibits contrasting bright and dark areas when viewed up close, appears pale...

This image shows an updated map of Saturn's icy moon Enceladus, generated by the Cassini imaging team. The map incorporates new images taken in 2008, with better image processing techniques. Comp...

Enceladus is a world divided.
